[0037] In the related art, the evaporator and condenser of a mobile air conditioner are installed on the housing by screws. Both the evaporator and the condenser are provided with first mounting holes, and the housing is provided with second mounting holes. When assembly is required, the operator aligns the first mounting holes of the evaporator and the condenser with the second mounting holes of the housing, and then screws in the screws to achieve fixation. However, manual alignment is required during the installation process. At the same time, displacement is likely to occur when screwing the screws, resulting in low installation efficiency.

[0038] In view of the technical problems involved in the related art, the present utility model proposes a fixing structure. The evaporator and the condenser are respectively arranged above and below the volute casing. The evaporator is limited by the limiting structure on the upper cover and the volute casing, and fixed by the locking structure. The condenser is limited by the limiting structure on the bottom shell and the volute casing, and fixed by the locking structure, and the installation is convenient and fast.

[0039] Refer to Figures 1 to 5 , the fixing structure includes an upper cover 100, a volute casing 200, a bottom shell 300 and an outer shell. The upper cover 100 is arranged above the outer shell, the bottom shell 300 is arranged below the outer shell. The upper cover 100, the outer shell and the bottom shell 300 jointly define the inner cavity of the mobile air conditioner. The volute casing 200 is arranged inside the outer shell and is located between the upper cover 100 and the bottom shell 300. The evaporator is arranged between the upper cover 100 and the volute casing 200, and the condenser is arranged between the volute casing 200 and the bottom shell 300.

[0040] It can be understood that the upper cover 100 is provided with a first limiting portion 110, and the evaporator is limited by the first limiting portion 110. The first limiting portion 110 is a first through hole, and a limiting column matching with the first through hole is provided on the upper part of the evaporator. When installing the evaporator, first place the evaporator on the volute casing 200, and then install the upper cover 100, align the first through hole with the limiting column and insert it.

[0041] It can be understood that a second limiting portion 210 is provided above the volute 200, and the second limiting portion 210 is an elastic buckle. The elastic buckle is provided with two latch blocks arranged side by side. The latch blocks are arranged in the vertical direction and can be deformed in the horizontal direction, that is, the latch blocks can swing left and right. After the buckle is deformed, it can reset without external force. The latch block is provided with a limiting protrusion, and a second through hole is provided in the lower part of the evaporator. The latch block can be inserted into the second through hole, and the limiting convex portion 211 can limit the evaporator. When installing the evaporator, align the second through hole with the second limiting portion 210 and insert it. The two latch blocks are deformed in the direction of approaching each other. When the limiting convex portion 211 passes through the second through hole, the two latch blocks reset, and the limiting convex portion 211 catches the evaporator to achieve fixation.

[0042] It can be understood that the limiting protrusion is provided with an inclined surface. The starting position of the inclined surface is located at the upper end of the latch block, and the inclined surface slopes downward and is located outside the latch block. The sides of the two latch blocks away from each other are the outside of the latch block. It should be noted that in some other embodiments, only one latch block can be provided, and the limiting convex portion 211 is a plastic part. Through the characteristic that the plastic part is easily deformed, the limiting convex portion 211 passes through the second through hole. After the limiting convex portion 211 passes through the second through hole, it becomes its original shape and catches the evaporator to achieve fixation.

[0043] It can be understood that a third limiting portion 220 is provided below the volute 200, and a fourth limiting portion 310 is provided above the bottom case 300. Both the third limiting portion 220 and the fourth limiting portion 310 are convex blocks. The convex block is provided with a limiting groove, and the limiting groove is located at the end of the convex block. The convex block abuts against the outer walls of the evaporator and the condenser, and the limiting groove is used to catch the evaporation pipe of the evaporator and the condensation pipe of the condenser. Multiple reinforcing ribs are provided on the side of the convex block away from the evaporator and the condenser.

[0044] It can be understood that a first locking portion 230 is further provided above the volute 200, and a second locking portion 320 is further provided above the bottom case 300. Both the first locking portion 230 and the second locking portion 320 are connecting blocks. The connecting block is provided with a third through hole, and both the evaporator and the condenser are provided with a fourth through hole. A screw can pass through the third through hole and the fourth through hole to achieve locking.

[0045] Referring to Figure 1 , the present utility model further provides a mobile air conditioner, and the mobile air conditioner includes the above-mentioned fixing structure, which can realize the quick positioning and fixation of the evaporator and the condenser.

[0046] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present utility model.
